JOHN FERDINAND CORDES, OF CHICAGO, ILLINOIS.

TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 758,050, dated April 26, 1904.

Application filed November 23, 1900. Serial No. 37,438. (No model.)

T0 all whom, it m/Ly concern:

Be it known that I, JOHN FERDINAND CORDES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates generally to temporary loose-leaf binders for holding orderblanks, freight-receipts, bills, or other sheets for current use and until they are ready to be transferred to permanent covers or binders of simpler and less expensive construction.

My invention also relates to a special form of temporary binders of the above-named class which employ impaling-posts supported upon a base-plate and a clamping-plate adjustably affixed to the impaling-posts and wherein the said posts may be adapted to hold either a greater or less number of sheets without projecting above the clamping-plate an objectionable distance.

The objects of my invention are mainly to connect the impaling-posts to the base-plate in a novel manner, to provide a strong light structure and a secure connection between the base-plate and posts to hold them truly in position thereon, and also to make the connection between the posts and base-plate such that the posts may be removed therefrom either to substitute posts of different lengths or to remove the posts and Sheets together, and thus easily transfer the sheets from the temporary binder to the permanent binder without removing the sheets from the posts.

My invention consists in certain features incident to the objects above named and to other objects, as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure lis a perspective view of the base-plate ofa temporary binder with the impaling-pins secured thereto in accordance with my invention. Fig. 2 is a longitudinal section of my binder with a short post secured thereto. Fig. 3 is a similar view of the bottom cover and baseplate of my temporary binder with a permanent binder and long bolt adapted thereto overlying the temporary binder, and Fig. 4

is a plan View of the preferred form of clamping-plate to be used with a temporary binder.

The base-plate A is made of a rectangular bar of thin light material, as strap-iron, or of still lighter material, as aluminium or wood liber, the thickness of the strip being such that a threaded hole therein would not provide a secure connection forl an impaling-post, and to make such-connection in a simple and effective manner the base-plate A is drilled or punched and metal th imble Bis passed through the said hole and riveted or upset to provide a secure connectiop therewith. The thimble B has a shoulder b to rest upon the outer face of the strip A and a cone b2, projecting above the said shoulder, to provide an extended longitudinal inner bore 3, which is threaded to provide a long bearing and secure connection with a corresponding]y-threaded section e at the lower end of the impaling-post E, and thus allow the said post to be easily attached and detached from the said plate and securely held thereon square with the plate when its thread ed end is screwed Within the thimble. Any number of impaling-rods, usually two, are secured to the base-plate, and the connection thus described of the base-plate to the rods Will always hold the rods parallel to each other and prevent them from being spread apart at their upper ends by a strain or blow which would be sufficient to bend the joint between base-plate and pin if the base-plate were made of thin material. The threaded connection between the end of the impaling-pin allows short pins to be first used when a small number of leaves only are to be held upon the binder, the ends of the short pins projecting but slightly above the clamping-plate H', and the capacity of the binder for holding a greater number of leaves may be readily increased by removing the short pins one at a time and substituting longer pins therefor which will project within a predetermined and unobjectionable distance from the clamping-plate, and so on until any convenient number of leaves may be added to the number held upon the Vbase-plate. The upper ends of the posts E have fiat sides e', which are adapted to receive a wrench which may be used to screw the posts into and out of connection to the base-plate and are also screw-threaded to receive the nuts f, which serve to hold the clamping-plate rigidly in place. Said clamping-plate may be of any preferred construction, preferably having slots 7L therein for the insertion of the impaling-posts without removal of the nutf. Three sizes of posts, as E E E2, are shown in the drawings. rlhe cone b2 of the thimble B projects above the base-plate a sufficient distance to allow the outer ends of the leaves to have a suitable space between them and the baseplate to allow the solid bulk of leaves to break and open up at the back, with the cone-points of the thimbles as a fulcrum, thus permitting the bound volume of leaves O to more freely open up than if they rested flat upon the baseplate and were held tightly against it by the clamping-plate.

With my improved screw-threaded posts and screw-thimble connection on the baseplate the leaves may be readily transferred in bulk from a temporary binder to a permanent binder of cheaper construction. A simple way to make the transfer yis to first unscrew one of the posts from the thimble of the baseplate and remove it therefrom and from the body of leaves and replace the temporary binder-post E with a permanent post E2, preferably having a thread e? at its upper end and a thread @3 at its lower end, the first only being passed through the holes in the leaves.

The bodyv of leaves O is then lifted a short distance above the base-plate A of the temporary binder, and one end of the base-plate A of the permanent binder is placed beneath the body of leaves with the threaded post-hole therein below the lower threaded end of the permanent binder-post E2 and the latter screwed into it.

AAn ordinary nut F and perforated clampingstrip H at the upper end of the permanent binder-post serves to hold the body of the leaves at one side securely to the base-plate of the permanent binder, as shown in Eig. 3 of the drawings. The temporary binder-post at the opposite side of the body of leaves is then removed therefrom in a like manner, and the corresponding end of the base-plate Al of the permanent binder is then placed beneath the body of leaves with its threaded post-hole opposite the threaded end of the permanent binderpost andthe latter screwed therein and the clamping-strip and nut on the upper end of the post and the nut screwed down thereon until the leaves are all tightly bound to the baseplate of the permanent binder. Other ways of transferring the papers from the'temporary to the permanent binder in a solid body by means of my removable posts will readily suggest themselves. Sectional posts have been heretofore used to partly carry out the object of my invention; but they are made to screw one upon the end of the other and to do this are necessarily made of a longer diameter than that of the standard size of post and of the holes provided in the leaves of sheets supplied by the trade for use upon temporary binders. The sectional posts are designed solely to obviate the use of long rods which will project beyond the clamping-plate suiciently to be in the way when in use and cannot be used in the manner herein described for transferring the leaves in a body from the temporary to the permanent binder.

1 claim as my invention and desire to secure by Letters Patentl. In a'temporary binder, the combination with an apertured base-plate, of axially screwthreaded thimbles permanently and rigidly secured in said apertures, a conical end on each which extends above the plate and acts y being conical and adapted to hold the contents of the binder out of contact with the baseplate, a post threaded at one end'to engage in said thimbles and angular at the other end and a clamping-plate provided with transversely-opening slots adapted to receive said i posts and means for locking said clampingplate to the post.
